Low noise, shock-absorbing speaker cabinet

ABSTRACT

Disclosed is a low-noise, shock-absorbing speaker cabinet, which includes a cabinet body, a face panel fixedly provided at the front side of the cabinet body for holding a speaker in a hole thereof, a line of first floor bearing portion formed on the bottom side of the face panel and a line of second floor bearing portion formed on the rear end of the bottom side of the cabinet body for supporting the speaker cabinet on the floor, and a suspension open space defined between the front bottom side of the cabinet body and the face panel to reduce floor contact area of the speaker cabinet so as to effectively eliminate noises and shocks and improve the output quality of the speaker.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates speaker systems and more specifically, toa speaker cabinet, which effectively reduces resonant noises and shocks,thereby improving the output quality of the speaker.

2. Description of the Related Art

Music is animal activity which involves structured and audible sounds,which is used for artistic or aesthetic, entertainment, or ceremonialpurposes. Listening music is the best simple way to release pressure.Following fast development of technology, CD stereo systems have beenintensively used in every family to substitute for conventionalbig-sized transistor radios. Nowadays, people are more critical on soundquality. Except the factor of the quality of the speaker, the quality ofthe cabinet is also an important factor that determines the soundquality of the speaker system.

Speaker cabinets vary in price. A pair of simple speaker cabinets mayvalue only few ten US dollars. However, a high quality speaker cabinetmay cost more than one thousand US dollar. The quality of a speakercabinet has a great concern with the measure of eliminating resonantnoises during output of sound. A high quality speaker cabinet has meansto eliminate shocks and to absorb/isolate sounds, thereby achievingperfect reproduction of original sound.

Speaker cabinet manufacturers are trying hard to keep creating newquality products. Taiwan Patent Publication No. M263706 discloses ashock-absorbing foot member for speaker cabinet. According to thisdesign, the shock-absorbing foot member comprises a stem and footpad.The stem has a threaded body and a conical tip at one end of thethreaded body. The threaded body is mounted with a block, a cushion, andnuts. The footpad has a top center hole for receiving the conical tip ofthe stem. Further, the conical tip of the stem is mounted with ashock-absorbing cap. The shock-absorbing cap has a center through holefort the passing of the threaded body of the stem. The top center holeof the footpad fits the contour of the shock-absorbing cap so that theshock-absorbing cap with the stem can be tightly secured to the footpad.During operation of the speaker, the shock-absorbing cap absorbs shocks.This design of foot member allows the user to shift the position of thespeaker cabinet.

Further, FIG. 1 illustrates a speaker cabinet constructed according tothe prior art. According to this design, elastic footpads are directlyadhered and fastened to the bottom wall of the speaker cabinet atdifferent locations. When the speaker cabinet is placed on the floor,the footpads support the speaker cabinet above the floor. These footpadscan absorb shocks in vertical direction. However, they cannot eliminateresonant vibration during sound output performance of the speaker.Because this design of speaker cabinet cannot eliminate resonantvibration, the speaker cannot achieve the best performance.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances inview. It is the main object of the present invention to provide aspeaker cabinet, which effectively reduces resonant noises and shocks,thereby improving the output quality of the speaker. To achieve this andother objects of the present invention, the speaker cabinet comprises acabinet body and a face panel fixedly provided at the front side of thecabinet body for holding a speaker in a hole thereof. The cabinet bodyhas a cross section smaller than the face panel. The speaker cabinetfurther has a line of first floor bearing portion formed on the bottomside of the face panel and a line of second floor bearing portion formedon the rear end of the bottom side of the cabinet body for supportingthe speaker cabinet on the floor, and a suspension open space definedbetween the front bottom side of the cabinet body and the face panel toreduce floor contact area of the speaker cabinet. Because the speakercabinet is kept in contact with the floor through the line of firstfloor bearing portion and the line of second floor bearing portion, thespeaker cabinet effectively eliminates noises and shocks and greatlyimproves the output quality of the speaker.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 2˜7, a low-noise, shock-absorbing speaker cabinet inaccordance with the present invention is shown comprised of a face panel1 and a cabinet body 2. The face panel 1 is provided at the front sideof the cabinet body 1, having at least one speaker 4 in at least onespeaker hole thereof. The cabinet body 2 is fixedly connected to theback side of the face panel 1, having a cross section smaller than theface panel 1.

The speaker cabinet further has a first floor bearing portion 31 formedon the bottom side of the face panel 1, a second floor bearing portion32 formed on the rear end of the bottom side of the cabinet body 2, anda suspension open space 33 defined between the face panel 1 and thefront end of the bottom side of the cabinet body 2.

Referring to FIGS. 2 and 3 again, when the speaker cabinet is placed onthe floor, the first floor bearing portion 31 and the second floorbearing portion 32 are disposed in contact with the floor. This linearcontact between the speaker cabinet and the floor results in excellentshock-absorbing and low-noise effects. Therefore, the design of thepresent invention effectively improves the output quality of the speaker4, eliminating the self-shocking drawback of the prior art multiplecontact points design during output of sound.

Referring to FIG. 4 again, the face panel 1 can be made having tworecessed holes 11 respectively formed on the two opposite lateral sidesthereof and two ornamental strips 12 respectively fitted into therecessed holes 11 to enhance the sense of beauty of the speaker cabinet.

Referring to FIGS. 4˜7 again, the face panel 1 can be made in acircular, square or rectangular shape illustrated in the drawings.Alternatively, the face panel 1 can be shaped like a star or flower. Thecabinet body 2 can be made in the shape of a cylinder, cube, quadraticprism, or triangular prism. Alternatively, the cabinet body 2 can beshaped like a star or flower.

A prototype of speaker cabinet has been constructed with the features ofFIGS. 2˜7. The speaker cabinet functions smoothly to provide all of thefeatures discussed earlier.

Although particular embodiments of the invention have been described indetail for purposes of illustration, various modifications andenhancements may be made without departing from the spirit and scope ofthe invention. Accordingly, the invention is not to be limited except asby the appended claims.
